Hello everyone!

I'm (relatively) new to optics, and almost clueless where to find the lens I need for my project. Thought someone may suggest something helpful.

I need a large lens (>7cm, ideally around 10cm), with about 25-30cm focal length, to focus parallel white beams to points in the focal plane.

The key point is the range of input angles. I want it large, like +-20 degrees, hopefully more. (this means the screen in the focal plane will also be large, that's ok)

I'm not interested in high resolution (very small point size). Perhaps interested in chromatic aberrations (their reduction).

I considered lens for telescopes, but they are just for different purpose. They make extremely small points (what I don't need), sacrificing angle range (that I really need). I didn't yet try any of them though.

Any ideas? Please.
